Portland and SF don't have fully legal and regulated drug supply so I'm not sure what your point is.

Drug prohibition is the entire reason that fentanyl is now in the drug supply and prohibition where supply is unregulated is a large reason for overdose deaths. Most overdose deaths are due to inconsistency in potency which would not be a problem if the supply were regulated. Compound that issue with the harm that the legal system does to someone with an addiction, essentially barring them from normal life if they have a conviction, and we have the recipe for disaster which is the current state of affairs. People with drug convictions are generally seen as having a scarlet letter of unemployability which generally keeps them in a state of addiction and/or homelessness and there is a massive stigma attached not only to drug addiction but mental health issues which usually go hand in hand. That makes it incredibly difficult to get proper treatment.
